@jpswift1 What is your experience with the Jet Dynamics ride plate for your FX-1?

I won't pull the cylinder(s) until I put the Yamaha 650 in my wife's ski. But out of curiosity, where can you buy a new Yamaha 701 oem crankshaft assembly for a decent price? Better than Partzilla.com:

Rear cylinder:

Front cylinder:

I cannot post up photos from my inspection camera because it is a Micro SD card and I can't find my adapter to full size SD card. However, I can describe an unusual thing I saw in the front cylinder. The top of the front piston had some fresh shiny "dings" in the very center where the spark...

When my wife and I bought her 1994 Square Nose Super Jet I assumed (and the seller did not disabuse me of my assumption) that it had the stock 701 engine in it. Well, when I eventually informed by a friend that it was, in fact, a Yamaha 650, I was pissed but it was too late to do anything with...

Thanks Mike. Can you also tell the year of manufacture?

What engine is this?

This is the type of dolly that our best jet skier buddy uses to load and to unload his ski from his receiver hitch hauler without backing his truck into the water. He lifts the aluminum dolly which is quite light out of the back of his pickup truck, then uses the winch to pull the ski off of...

Now this post is gold for me. And timely because I have two sets of sponsons to install yet.

Well, you have shamed me many times with your build (for instance, I won't show this thread to my wife), but your labeling of your electrical panel really puts me to shame . . . Quality shows. And your work shows it.

Post up a photo of the EZ ski please.

Go to www.waxracingproducts.com and talk to wax or pm him here: @waxhead I have a Factory B Pipe and wax’s manifold and head pipe for the 2019 Super Jet which I may put on this weekend. I also have wax’s intake manifold for dual SBN38 carbs to put on the 550sx.

Beautiful work! I bought my base molding from "Mr. Molding." The owner told me, "Cut your best, and caulk the rest." Worked for me.

The Christ walked on water. So, I am pretty sure that he has been, is or will be a stand up jet skier. In fact, I am pretty sure that He won't be mad if I add this to His Beatitudes: "Blessed are those that restore vintage stand up jet skis, For they promote the Joy of future riders."

Here's your drool thread: https://www.x-h2o.com/threads/mini-monster.194696/page-5 These are the waxracingproducts.com rear sponsons on the @Aquaholic (i.e., "Braap Doctor") 550sx. I also have @waxhead's rear sponsons on my FX-1, below, and they are fantastic. I will eventually put...

Don't hold your breath waiting for one: https://en.wikipedia.org/wiki/Nikola_Corporation Liquid fuel is still the best source of energy. And where a light weight power plant is desirable, for instance in watercraft, 2-stroke engines are still the best.

The ski does not porpoise at all and really does not exhibit any handling "problems" whatsoever.

Thanks BK. But now I am confused. I was told just the opposite. Why do handling before power?

I think I will do one thing at a time. Change out pole first. Then install pipe. I will come back to changing intake grate and ride plate again after that.
